Do I need to remove mold from my building?

Yes, mold removal is essential for both health and property protection. Even small amounts of mold can cause respiratory problems, allergic reactions, and more serious conditions like pulmonary fibrosis with prolonged exposure.

Mold thrives in warm, damp environments and can grow virtually anywhere in your building:

• Bathrooms - showers, tubs, sinks, toilets
• Kitchen areas - refrigerators, pantries, microwaves
• Living spaces - mattresses, couches, curtains, windowsills
• Hidden areas - air ducts, vents, insulation, chimneys
• Decorative elements - indoor plants, damp furnishings

Health symptoms from mold exposure—including congestion, coughing, and sore throat—are frequently mistaken for common colds. However, these persistent symptoms often indicate a mold problem requiring attention.

Regular maintenance by professional housekeepers and periodic high-pressure cleaning services are crucial preventive measures against mold growth. These professionals can access hard-to-reach areas and apply specialized techniques to eliminate mold and prevent future outbreaks.

• Are they licensed mold remediation contractors?

• Are they certified to remove mold?

• Are they insured?
